I have one who is 3 months old whose toes look very similar. It is not due to a vit deficiency though. It's as a result of balance problems that she has due to being one-legged. My pheasant also has this type of toe problem too, also as a result of balance issues due to an orthopedic deformity in her neck and spine. The leg on your bird actually looks a bit off up near the hock, which makes me wonder if possibly she has something else going on. Do her hips feel inline, how about her hock, any tendon problems? Also, despite the obvious gait problem with the toes, do you notice that she walks with her leg out of alignment....it looks like she might. I thought about trying to correct it in my one-legged chick but this is the way she compensates and I felt it would just stress her. I give mine a joint supplement to help with, hopefully, combatting subsequent joint problems that we will probably encounter. I would just watch her feet to make sure she doesn't acquire any sores from the position, apply bag balm on the foot (top and bottom) and toes to help keep skin tissue healthy and make sure diet is good. Also, make sure she has comfortable places to lay and she made need to be kept safer than the norm.
